Bleeding more heavily.

Spotting at first dr appt on last Thursday. Was sent for bloodwork and us. Got precious pictures of baby withheartbeat at 160. Since then i had been having off and on spotting with brown discharge and once with a tad bright red. Then on today i wake up and it was heavy brown dc. Called OB him and his nurse were not in so receptionist urged me to go to the ER. Im so sick of this worry. Anyone else with similar issues at 9 week plus 5
